Wife and I have a 2019 Bolt with the separate Heat and AC buttons. This time of year I like to run just “vent only” for fresh air, no heat no ac. So I turn it “on” with the main button, with both heat and a/c turned off. Yet the heater clearly starts to run and heat up the car if I turn the temp knob above ambient, and the ac kicks on if I turn it down... no matter what I do it seems I can’t get just pure outside air to flow through the cabin?

I am very mechanically inclined. I’ve built motors. I’ve literally sat in my garage playing with this and can verify the ac compressor runs when turning the knob down, and the resistive heater seems to kick on when turning it up. The air the comes out the vents absolutely changes temperature also.

The weird thing is it doesn’t use nearly the same amount of battery power as it would if I actually turn on heat or ac - the graph shows only a tiny sliver used for it. If I were to actually turn on heat or ac, the graph would show much higher %.

This may be your problem. From the owner's manual:
Auto Defog : The system will monitor high humidity inside the vehicle. When high humidity is detected, the climate control system may adjust to outside air supply and turn on the air conditioner or the heater. The fan speed may slightly increase to help prevent fogging. When high humidity is no longer detected, the system will return to
its prior operation. To turn Auto Defog off or on, see “Climate and Air Quality” under Vehicle Personalization -143.

This morning, about halfway to work, my iPhone disconnects from CarPlay. a few minutes of listening to SiroiusXM later, before I decide to do a hard reboot, the system reboots spontaneously. Once it does, CarPlay starts back up.
On the way home form work, about 2 minutes before I arrive home...

When I use the push to talk button, it brings up my recent calls on my phone but does not prompt me to speak. Has anyone else run into this or have a fix? I tried bringing it into the dealer and they couldn't figure it out.

One of my 2017 Bolt FOBs is intermittent. Twice now it has somewhat died for a short time and then been fine. The battery is ok. Last week I went to get in the car using the door button. That worked, but the car alarm then went off. I used the FOB to silence it. Then I had to put the FOB...

I've posted here before about range issues with my 2017 Bolt. These lead to 38 days out of service and a full replacement of the battery. This was in April and May. Visit # 1 - 3-4hrs and visit #2 - 38 days. See previous thread...

24000km and 12 months old, noticed strange creaking noises coming from
Rear of vehicle at low speeds in reverse or forward motion. Not just on bumps, more just in motion. Dealer needed 1 week to diagnose and I’m getting a new axel next week. Strange. Noise sounded like two heavy metal hangers...
